Arctic this week added its first passive cooler that is compatible with AMD’s AM4 processors into its lineup of products. The Alpine AM4 was designed for APUs and CPUs that dissipate no more than 47 W, which is common for modern mainstream chips that feature reduced TDP.

The Arctic Alpine AM4 passive cooler is made of black anodized aluminum, features 21 rather thick fins, and weighs 557 grams. The heat sink has a z-height of 81 mm and measures 100 × 100 mm on its sides, so it has to be installed into relatively spacious cases. Speaking of installation, it is worth mentioning that the Alpine AM4 ships with four screws with springs, so the installation of the device is fairly simple. To further things simplify, the cooling system comes with pre-applied MX-2 thermal compound. As a small bonus feature for those who want peace of mind, the passive cooler is covered by a six-year warranty as if a solid piece of aluminum could break down.

Arctic recommends to use the Alpine AM4 with AMD’s energy efficient APUs, such as the AMD’s Ryzen 3 2200 GE and Ryzen 5 2400GE, but the cooler will also handle AMD’s 65 W APUs and CPUs that can be programmed to limit their TDP to 46 W (at the cost of their frequency). Therefore, it is now possible to build a fanless PC based on a fairly wide range of AMD’s Ryzen 1000-series and 2000-series CPUs.

Arctic will start selling the Alpine AM4 passive coolers in the coming weeks. Pricing is not yet known, but judging by the simplistic construction of the product, do not expect it to cost significantly more than $20. In fact, Arctic’s currently-available Alpine passive coolers for Intel processors retail for €12.99 ($15.2) in Europe.

    And much more compact than any tower cooler. It's meant for small cases like ITX cases where the side ventilation + exhaust fan is good enough to work with this. It's actually a good way to avoid dust clogging up the heatsink fins that you'd get with a heatsink fan after a year or so of continuous running. Reply

    For some of their workstation and smaller form factor machines, Dell, HP and Lenovo use this kind of passive heat sink with a custom duct connected to the exhaust fan. And it works well. Basically you increase the CPU cooling ability of the otherwise passive heatsink while having less noise and one less fan to worry about. Reply

    if those three do it , then its a cost saving exercise. First time I've heard anyone mention the configurable tdp , I might have bought amd if that was explained in reviews, but they only ever go for max o/c and powah. Reply

    How is it different from using a big tower cooler WIITHOUT fan? Those heat sink does not look that good to me. Reply

    Pre-applied thermal compound, eh? This could have been made even more foolproof (with extra cost) by including a reusable graphite/graphene pad like the ones IC recently released. Reply

    Not impressed. I have a passive NoFan cooler on my i7-2600k (95W TDP) and have it overclocked to 4GHz and it runs at around 40c in the summer with general computer usage. Reply
